Study on Sulfur Control Technology for Non-Oriented Electrical Steel

Abstract:

In cognizance of the problems of low desulphurization rate for hot metal, large sulfur-recovery in converter, as well as high sulfur content in products when producing non-oriented electrical steel with vanadium-content hot metal, countermeasures have been carried out. Sulfur content in non-oriented electrical steel is decreased obviously with the study on technologies of desulphurization for hot metal with vanadium & titanium, sulfur-recovery control in converter, and desulphurization in RH refining process as well. The results of industrial tests show that the rate of w（S）≤0.008 % is as high as 100 %, and the rate of w（S）≤0.005 % reaches 91.43 %. And besides, sulfur mass fraction is 0.004 2 % on average (0.001 9 %~0.006 9 %).
